Breath Effect - Free Blend File

Hey everyone, I'm dropping a node group that I've used in some of my projects to create a heavy "breath" effect. You can add it to your project by appending the plane object into your blend file.

The effect is quite simple but I figured it might be useful for those not too familiar with procedural textures. Plus it's a pretty quick, drag and drop solution. Just position the plane where you want the effect, and keyframe the transparency value in the node group to match your animation.

Here are some tips on using it

- The controls on the node group itself are just basic controls. Generally you want to keyframe the transparency value. 0 will set it to invisible, while higher values will be more visible. The emission value can usually be set to 1 but you might want to adjust it depending on your lighting setup.

- For more controls you'll need to open up the node group. The noise texture can be adjusted to change the shape or appearance. NOTE: The texture coordinate node has a driver setup on it. It's just a simple equation that takes the current frame number and divides it by a certain amount. This causes the noise texture to be animated automatically. If you don't like the speed you'll have to adjust the driver or just delete it and manually keyframe it yourself.

- The color ramp on the mask group will let you adjust the shape and how harsh the edges are. Again the default is setup for a decent fade from the edges but feel free to adjust to your tastes.

That's pretty much it, no need to tag or credit me but would like to see what you come up with using it! Happy blending <3
